Is alos Palsar data free?
Since ALOS-1 was a Japan Aerospace Exploration Agency (JAXA) mission, the Japanese government owns the data and required anyone wishing to use PALSAR data to first submit a proposal. Non-U.S. researchers also had to pay a fee for each scene they wanted.
What is alos Palsar?
PALSAR was one of three instruments on the Advanced Land Observing Satellite-1 (ALOS), also known as DAICHI, developed to contribute to the fields of mapping, precise regional land-coverage observation, disaster monitoring, and resource surveying. ALOS was a mission of the Japan Aerospace Exploration Agency (JAXA).
Is alos Palsar 2 free?
To be more specific, free and open access to the wide-swath observation data from the L-band radar satellites, ALOS (ALOS/AVINIR-2, PALSAR) and ALOS-2 (ALOS-2/ScanSAR) will be made available.
What is the resolution of Sentinel 1?
Sentinel-1 has four operational modes: Strip Map (SM) Mode features 5-by-5-metre (16 by 16 ft) spatial resolution and an 80 km (50 mi) swath. Interferometric Wide Swath (IW) Mode features 5-by-20-metre (16 by 66 ft) spatial resolution and a 250 km (160 mi) swath.
What is alos in healthcare?
The average length of stay in hospitals (ALOS) is often used as an indicator of efficiency. All other things being equal, a shorter stay will reduce the cost per discharge and shift care from inpatient to less expensive post-acute settings. The ALOS refers to the average number of days that patients spend in hospital.
What are the advantages of ALOS DEM data?
The results show that ALOS DEM is capable of extracting drainage networks within the Iishana sub-basin. nformation on remote sensing data used in the study. A complex mesh of interconnected drainage network systems in the study area. The wetness index (NDWI) image used to aid drainage delineation.
What is the difference between Sentinel-1 and 2?
Sentinel Missions The first Sentinel-1 satellite was launched in April 2014. The objective of Sentinel-2 is land monitoring, and the mission will be composed of two polar-orbiting satellites providing high-resolution optical imagery. Vegetation, soil and coastal areas are among the monitoring objectives.
What is C-band in Sentinel-1?
Band. A selection of wavelengths or range of radar frequencies. For example Sentinel-1 operates at C-band (central frequency of 5.404 GHz). Other spaceborne SAR’s operate at L-band (1.3 GZ) or X-band (9.6 GHz).
How is alos calculated?
Length of stay is a term which is used to calculate a patient’s day of admission in the hospital till the day of discharge i.e. the number of days a patient stayed in a hospital for treatment. ALOS is calculated by dividing total inpatient days by total discharges.
Why is alos important to hospitals?
There are certain critical key performance indicators which help impact both patient satisfaction as well as hospital profitability. One of these indicators is the average length of stay (ALOS). ALOS is the average number of days a patient stays in a hospital.
How do I read a .DEM file?
How to Open
- Global Mapper: File > Open Data File(s)and select the appropriate .dem file.
- ArcMap: In ArcToolbox, go to Conversion Tools > To Raster > DEM to Raster.
- ArcGIS Pro: Use the Copy Raster tool (DEM to Raster is now depracated)
- QGIS: while GDAL library supports USGS DEMs, not functional in QGIS 2.18.
